A supersonic combustion apparatus including a fixed geometric nozzle having a converging area, throat, and a diverging area, at least one movable combination of a fuel injector and an oxygen injector where the combined fuel injector and the oxygen injector is located within the divergent area of the fixed geometric nozzle, and an exit plane adjacent and downstream to the diverging area. The exit plane Mach speed is varied by heat addition in the diverging area by introduction of a combustible fuel through the fuel injector and oxygen through the oxygen injector and then axially aligning and positioning the combination of the fuel injector and the oxygen injector along the length of the diverging area to obtain a stabilized flame at the exit plane.

Variable supersonic mach number air heater utilizing supersonic combustion

A supersonic combustion apparatus and method for using the same including a fixed geometric nozzle having a converging area, throat, and a diverging area, at least one fuel injection means and at least one flame stabilization means located in the divergent area, and an exit plane adjacent and downstream to the diverging area, where an initial first injection/flame stabilization means is located in the diverging area and the exit plane Mach is varied by heat addition in the diverging area by at least one more fuel injection means.
